NEW YORK--(BUSINESS WIRE)--Pfizer Oncology will present data from across its portfolio, including results from long-term follow-up of Aromasin^® (exemestane tablets) in a study of early breast cancer,¹ updated study results from a Phase 3 study of Sutent^® (sunitinib malate) in pancreatic neuroendocrine tumors (NET),² and early-stage research of investigational agents PF-02341066³ and figitumumab (CP-751,871)⁴ in patients with non-small cell lung cancer (NSCLC). These data, and over a dozen additional abstracts covering Pfizer agents, will be presented at the ECCO 15/ESMO 34 bi-annual meeting in Berlin, Germany from September 20 to September 24.

“Pfizer is conducting research to identify clinical benefits for targeted patient populations with investigational compounds like cMET/ALK inhibitor, while continuing to study drugs like Aromasin through their entire life cycle to ensure we provide maximum support and information to patients and healthcare providers about our cancer products,” said Dr. Mace Rothenberg, senior vice president of clinical development and medical affairs for Pfizer’s Oncology Business Unit.

Featured Data Highlights

At the meeting, Pfizer will present new 91-month median follow-up data from the Intergroup Exemestane Study (IES) study (Abstract #5010; September 22) which is evaluating the clinical benefits of switching women to Aromasin after two to three years of tamoxifen versus continuing women on tamoxifen for a full five years of therapy.¹ IES, a randomized, double-blind, multinational trial of postmenopausal women with hormone sensitive early breast cancer,⁵ enrolled 4,724 patients. IES is a landmark trial with the longest follow-up of endocrine treatment in the adjuvant switch setting.⁶

New study results from an expansion cohort of a Phase 1 study evaluating the investigational agent PF-02341066 in patients with NSCLC carrying the ALK (anaplastic lymphoma kinases) fusion gene will be highlighted in the “Best of 2009” Presidential Plenary session Thursday, September 24 (Abstract #6G).³ PF-02341066 is a selective ATP-competitive small molecule inhibitor of both c-MET/HGF receptor and ALK tyrosine kinases and their oncogenic variants. PF-02341066 is the first agent in clinical development that selectively targets a unique genetic feature found in several types of cancer, echinoderm microtubule-associate protein-like 4 (EML4)-ALK translocation, present in approximately 3 - 7 percent of NSCLC patients.⁷

In addition, final results will be presented from a Phase 3 trial (Abstract #6.502, September 23), which was discontinued in January 2009 following the recommendation of an independent Data Safety Monitoring Board (DSMB) after finding no evidence of improvement in the primary endpoint of survival in patients with advanced pancreatic cancer treated with axitinib and gemcitabine, compared to gemcitabine alone.

About Sutent® (sunitinib malate)

Sutent is an oral multi-kinase inhibitor approved for the treatment of gastrointestinal stromal tumor (GIST) after disease progression on or intolerance to imatinib mesylate and advanced / metastatic renal cell carcinoma (RCC).

Sutent works by blocking multiple molecular targets implicated in the growth, proliferation and spread of cancer. Two important Sutent targets, vascular endothelial growth factor receptor (VEGFR) and platelet-derived growth factor receptor (PDGFR), are expressed by many types of solid tumors and are thought to play a crucial role in angiogenesis, the process by which tumors acquire blood vessels, oxygen and nutrients needed for growth. Sutent also inhibits other targets important to tumor growth, including KIT, FLT3 and RET.

Important Sutent (sunitinib malate) Safety Information

Women of child bearing age who are (or become) pregnant during therapy should be informed of the potential for fetal harm while on Sutent.

Decreases in left ventricular ejection fraction (LVEF) to below the lower limit of normal (LLN) have been observed. Patients with concomitant cardiac conditions should be carefully monitored for clinical signs and symptoms of congestive heart failure.

Patients should be monitored for hypertension and treated as needed with standard antihypertensive therapy. Complete blood counts (CBCs) with platelet count and serum chemistries should be performed at the beginning of each treatment cycle for patients receiving treatment with Sutent.

The most common adverse reactions in advanced RCC and GIST clinical trials were fatigue, asthenia, diarrhea, nausea, mucositis/stomatitis, vomiting, dyspepsia, abdominal pain, constipation, hypertension, rash, hand-foot syndrome, skin discoloration, altered taste, anorexia and bleeding.

About Aromasin® (exemestane tablets)

Aromasin is the only aromatase inhibitor indicated for sequential therapy in postmenopausal women with HR positive early breast cancer after two to three years of tamoxifen for a total of five years of adjuvant therapy. The use of Aromasin in this setting is supported by the landmark IES trial. Aromasin is also indicated for the treatment of advanced breast cancer in postmenopausal women whose disease has progressed following tamoxifen therapy.

Important Aromasin (exemestane tablets) Safety Information

Aromasin should not be used in women who are premenopausal, are nursing or pregnant, have a known hypersensitivity to the drug, or are taking estrogen-containing agents. Dose modification is recommended for patients who are receiving certain medications, including strong CYP 3A4 inducers. In patients with early breast cancer, elevations in bilirubin, alkaline phosphatase, and creatinine were more common in those receiving Aromasin than either tamoxifen or placebo. Reductions in bone mineral density over time are seen with the use of Aromasin.
